WorkCentre C2424 Service Manual
Check Shafts Menu
Deskew Shaft
Runs the media path drive train and engages the deskew clutch on the fly then disengages the
clutch. The test is repeated in both directions to determine clutch characteristics, steady state
drive requirements, bearing status, etc.

0
Time to CCW On
peak fe (sec).
0.01 to
0.04
Reports how long it takes the MP motor servo
system to react to the sudden addition of the
deskew shaft load.
Larger values may show a slipping/slow to
engage clutch.
1
CCW On peak fe.
370 to
980
Reports peak effort needed to accelerate the
deskew shaft load. A smaller value could
indicate a slipping clutch.
2
CCW On fe settling
time (sec).
0.0 to
0.25
Reports the time it takes the MP motor servo
system to "settle down" after the sudden
addition of the deskew shaft load.
A longer time could indicate a looseness in the
deskew shaft assembly or a slipping clutch.
3
CCW On average fe.
250 to
600
Reports the average effort required to rotate
the deskew shaft in the CCW direction at a
constant velocity.
An unusual value could indicate a difference in
the composition and/or number of the rollers,
the nip pressure, or out of range mechanical
dimensions due to wear or contamination
(such as paper dust increasing the effective
diameter of a roller).
4
CCW On fe ripple.
80 to 300
Reports the variation of effort required to rotate
the deskew shaft in the CCW direction at a
constant velocity.
A larger value could indicate particles in the
gears or non uniform contamination of a roller
(causing a lump).
5
CCW Off fe settling
time (sec).
.10 to .20
Reports the time it takes the MP motor servo
system to "settle down" after the sudden
release of the deskew shaft load.
A larger value can indicate a slow to release or
dragging clutch.
6
Time to CW On
peak fe (sec).
0.01 to
0.06
Reports a time that indicates how long it takes
the MP motor servo system to react to the
sudden addition of the deskew shaft load.
Larger values may indicate a slipping or slow to
engage clutch.
